M1XRF2H Installation Manual

OVERVIEW
The
"2H"
model of the ELK-M1XRF Wireless RF Receiver (full part # ELKM1XRF2H) allows the ELK-M1 and ELK-M1EZ8 Controls
to accept specific models of Honeywell (Ademco) 5800 style wireless transmitters. Refer to the list of compatible transmitters
elsewhere in the manual. Regardless of model, an M1XRF receiver attaches to the four (4) wire (keypad) data bus and integrates
in much the same way as a hardwired zone expander, with the exception that a single M1XRF can handle up to 144 wireless zones
(e.g. transmitter sensors or points). Benefits of operating from the data bus are: 1) The receiver can be installed virtually anywhere
in a building up to the maximum distance of the data bus. This provides optimum convenience and coverage. 2) Multiple receivers
(up to 11 total) can be connected to a single control providing even greater coverage as well as redundancy. Using multiple receivers
it is possible to cover hundreds if not thousands of square feet with a receiver placed in strategic locations.
Another strong point of the M1XRF receiver is that all transmitter programming and enrollment data gets stored in the control panel,
not in the receiver(s). This provides two advantages: 1) Multiple "redundant" receivers can be deployed in a building and a transmitter
only need be enrolled one time. Even portable devices such as Keychain Remotes work perfectly regardless of which receiver
picks up the transmission. 2) And should a receiver ever become damaged or need replacement it is not necessary to re-enroll
the transmitters. Simply replace the receiver and perform a data bus enrollment of the receiver to the control panel.
IMPORTANT: As this time Elk produces two different models of Wireless (RF) Receivers. The M1XRF2H, designed for Honeywell
(Ademco) wireless transmitters, and the M1XRF2G, designed for GE (Caddx) wireless transmitters. YOU MUST HAVE THE
CORRECT MODEL RECEIVER TO MATCH THE BRAND OF TRANSMITTERS YOU ARE INSTALLING. It is possible to combine both
receiver models on an a single M1 Installation and use a mix of both brands of transmitters. But extreme care must be exercised
to assure that each transmitter brand is within range of it's respective receiver model. In other words, the receivers are
physically and electronically different and can only receive the transmissions of their particular brand transmitters.
NOTE: The "2H" suffix on the M1XRF part number refers to Dual (2) antenna and Honeywell (Ademco)
5800 Style Sensor compatibility.
